Title: Server based voice call offer while telephone in data session
Inventor: MACAULAY ROBERT PAUL
IPC: H04M1/72403
Filed: 1998-06-05
Abstract: During the occurrence of an incoming voice call to a portable telephone handset within an in building telephone system, a method is disclosed for offering the voice call while the called handset is in a data session with an application.      In such a case, the data session is interrupted and the handset display and softkey information is saved to memory. The name or number of the calling party is then written to the display of the called handset while the incoming call is offered to the user. A call acceptance signal from the called handset results in the establishing of a voice communication connection between the handset and the calling party. Independent of whether the incoming call is accepted or rejected by the user of the called handset, the saved display and softkey information is restored to the called handset and the data session is resumed between the portable handset and the application once the selection is made.

Title: Sustained release formulation containing dfmo
Inventor: WEIS ALEXANDER
IPC: A61K9/26
Filed: 1997-10-31
Abstract: Preparations comprising a capsule, tablet or other dosage form containing a core of different types of DFMO are provided. These preparations are capable of providing for the direct and constant delivery of DFMO to the entire GI tract or just the colon and rectum. The DFMO-containing granules include granules specially formulated to achieve rapid DFMO release, and granules formulated to achieve slower DFMO release and/or granules formulated for gastric, enteric or colorectal release. Methods of using the preparations to flood the GI tract with relatively constant levels of DFMO may thus be provided. The ratio of the (+) to the (-)-enantiomeric forms of DFMO in the granules will be controlled so as to enhance the pharmacological profile and reduce toxicity of the preparation relative to racemic DFMO. Preparations and methods for achieving systemic delivery as well as direct colon delivery of DFMO are also described.

Title: Communications signal splitter and filter
Inventor: HUMPHREY LESLIE DEREK
IPC: H04L1/00
Filed: 1998-09-21
Abstract: A splitter separates telephony traffic (POTS) from digital subscriber line (ADSL) traffic occupying a higher frequency band. The splitter comprises a low-pass filter for passing the telephony traffic, the low-pass filter being operable to vary its filtering response between a first low-pass response for use during telephony speech traffic, and a second, more restrictive, low-pass response for use during at least part of the time that telephony signalling traffic is present. During speech traffic a filter is used which provides a good impedance match with a telephony terminal or linecard so as to minimise detrimental effects on sidetone and echo performance which may impair a user's speech quality. The filter response can be varied according to a detected property of the telephony traffic, such as amplitude or rate of change of amplitude of the traffic.

Title: Method and apparatus for selectively transmitting packets of message data to a remote communication station
Inventor: JOHANSSON CARL FREDRIK
IPC: H04L12/56
Filed: 1997-09-26
Abstract: Apparatus, and an associated method (110), selectively transmits packets of message data between a sending (12) and a receiving station (14). When a packet of message data (22) is received at a receiving station (14), the receiving station (14) acknowledges reception thereat of the packet with an acknowledgment response signal (42), transmitted back to the sending station (12). If the sending station (12) fails to detect an acknowledgment response signal (42), a packet of activity-request data (72) is sent to the receiving station (14). If the receiving station (14) fails to acknowledge reception of the packet of activity-request data, a determination is made that the receiving station would be unlikely to be able to receive an additional packet of message data (22). A channel to be used to transmit the packet of message data (22) can instead be reallocated for other purposes.

Title: Code wrapping to simplify access to and use of enterprise java beans
Inventor: THEIVENDRA LEONARD W
IPC: H04L29/06
Filed: 1999-08-20
Abstract: An improved method to access software components on a server network, such as enterprise beans according to the Enterprise JavaBeans architecture, by using a wrapper called an Access Bean. Access Beans hide the home and remote interface methods of an Enterprise JavaBeans server from a client program so that the task of consuming an enterprise bean is one of consuming a standard Java bean. The home interface method of the enterprise bean is mapped to appropriate constructors in the Access Bean; and the remote interface method of the enterprise bean is mapped to Java Beans methods which in turn call the corresponding business methods on the enterprise bean. More than one type of Access Bean permits caching of attributes of the enterprise bean and indexing the cache so that a plurality of instances of an enterprise bean can be efficiently supported.

Title: A system and method for providing high terminal coupling loss in a handsfree terminal
Inventor: FORRESTER CHRISTOPHER MICHAEL
IPC: H04M9/08
Filed: 1998-02-24
Abstract: A method of increasing the terminal coupling loss in a digital half-duplex handsfree terminal is provided. When the terminal receive channel is active an idle code which is effectively zero is transmitted by an idle code generator.  When the terminal transmit channel is active a normal speech signal is transmitted. To determine which channel is active, a receive speech signal level is measured at the receive channel input, and a "virtual" transmit speech signal is computed from a signal in the transmit channel before the idle code generator.
